Source: VishayVishay Intertechnology, Inc. has introduced reportedly the industry’s first bi-directional 1500 W surface-mount PAR®transient voltage suppressors (TVS) in the low-profile eSMP™ SMPC (TO-277A) package. With their low height of 1.1 mm typical, devices in the TPCxxCA series offer a 52% lower profile than TVS in the traditional SMC package, while providing a 38% smaller footprint to reduce total volume by 70%. For designers, this high power density saves board space for lower system costs.

For high temperature stability in high-reliability conditions, the Vishay General Semiconductor TVS features a patented PAR construction for a temperature range of −65° C to +185° C. The TPCxxCA series offers breakdown voltages from 11 V to 36 V, excellent clamping capability from 15.6 V to 49.9 V, low leakage current, and very fast response times.

The TVS components are designed to protect sensitive electronics against electrostatic discharge (ESD) and voltage transients induced by inductive load switching and lightning. Ideal for automated placement, the TVS meet MSL level 1 standards per J-STD-020, and are RoHS compliant and halogen-free. The devices are available in AEC-Q101-qualified versions.

Samples and production quantities of the new TPCxxCA series are available now, with lead times of eight weeks for large orders.
